After returning to the physical world, Aang calms the attacking spirit, who was upset that the nearby forest he watches over was destroyed by the Fire Nation.

In preparation for the chief's secret mission of infiltrating the Fire Navy, Sokka clashes with a Northern soldier named Hahn before realizing he is Yue's fiancé.
